Garbage penetrating fluid treatment method

Abstract

The invention discloses a garbage penetrating fluid treatment method. The treatment method comprises the following steps: S1, preparing a primary concentrated solution; S2, preparing a secondary concentrated solution; S3, preparing deammoniated water and a secondary product ammonium sulfate solution; S4, preparing electrolyzed water; and S5, preparing discharge water; the method has the beneficialeffects that a DTRO membrane system and a COD membrane system are combined for use, meanwhile, the hollow fiber membrane forms deammoniated water and an ammonium sulfate solution, then the deammoniated water is electrolyzed, and the purification effect is achieved; a quartz sand filter is used for flushing and back flushing, and pure garbage penetrating fluid is obtained; an alkaline environmentis utilized to enable ammonia nitrogen to be in a free state, so that multilayer recovery is realized; an automatic scraper is used for filtering, so that influence factors on ozone catalysis are reduced; meanwhile, ozone catalysis is adopted, so that the content of organic matters in the electrolyzed water is reduced, and the SS value of edema suspended matters is reduced.

Description

technical field [0001] The invention relates to the field of garbage environmental protection treatment, in particular to a treatment method for garbage permeate. Background technique [0002] In recent years, with the acceleration of my country's urbanization process and the gradual improvement of people's living standards, the output of urban domestic waste has continued to increase; the main treatment methods for domestic waste include recycling, composting, incineration, and landfill. High economy, this method is often used in developing countries and underdeveloped areas to deal with domestic waste; however, due to the degradation of the waste dump during the landfill process of waste, factors such as atmospheric precipitation, groundwater influx and surface runoff are inevitable A large amount of landfill leachate will be produced. Landfill leachate contains a large amount of organic matter, salt and heavy metals, etc. It is recognized as a kind of refractory organic wa...

Problems solved by technology

Although sawdust material is used to fill the filter layer, and at the same time, the filter residue is used as raw material to prepare cake fertilizer, so as to realize the complete treatment of garbage permeate; however, it is not considered that when the SS value of the suspended solids in the garbage permeate is too high, the suspended solids are easy to clog The gaps formed by the sawdust will lead to the blockage of the filter layer and damage the device; at the same time, the high SS value will easily lead to excessive organic content in the discharged water; and in the above-mentioned invention, the removal of heavy metals and the recovery of other impurity ions are relatively narrow, and only ammonia nitrogen is recovered. Elements, can not be recovered in multiple levels Recoverable metal ions and non-metal ions in garbage permeate
